Remove the index.php from the CI frame URL under nginx

The default URL rule for the CI framework is the entry file with the app, for example:

Example.  COM/index.  PHP/News/article/my_article          

In the above URL with the portal file index.php, such a URL rule is not friendly to the search engine, then how to remove the index.php it?
Apache Environment:
Use the. htaccess file to set some simple rules to remove it. The following is an example of using the "negative" method to redirect non-specified content:

Rewriteengine onrewritecond!^ (index\.php|  Images|  Robots\.txt)rewriterule^ (. *)/index.  PHP/[L]              

If your project is not in the root directory, please change the above sentence to read:

Rewriterule^ (. *)$ index.  PHP/[L]       

In the above example, any HTTP requests that can implement any non-index.php, images, and robots.txt are directed to index.php.

Nginx Environment:
Modify the Nginx configuration file and add the following code to the server segment:

Location/{
    
Index index.php INDEX.HML index.htmIf  (-f $request _filename/index.php)  { rewrite (. *) $1/index.php ; } if  (!- E $request _filename { rewrite  (. *)/index.; }}          /span>
